Transactions With Variable Number Of Inserts
Nov 30, 2004
I'm stumped how to achieve my goal using stored procedures. I have a front end application that calls stored procedures to insert data. For example, customer pays a bill. To complete the payment process a command in the app is run which calls a stored procedure to insert a tender record and a second stored procedure to insert a transaction record. A customer can pay one to many bills at one time so the number of times the insert stored procedures are called is variable. I want to be able to use the begin transaction, commit and rollback statements so if there's a problem inserting a record all the inserts are rolled back. Previously the app used the visual basic begin transaction, commit, rollback, statements however I want to now use SQL stored procedures for inserts and updates. I've been struggling with this for some time and hope someone can help me.

G'day,
I have a table with a primary key being a bigint and its set to auto increment (or identity or whatever ms calls it). Is there anyway I can get the ID number that will be assigned to the next Insert before I insert it? I want to use that ID number within another field when inserted.
I hope that makes sense.
Thanks for any help.

Hey,
Is there somewhere in MSDE (or SQL) where you can see how many transaction are made to a sertain database or by a sertain user? At this way i could figure out witch database/user uses most (or least) recources (cpu) over a period of time.

I have created a kind of search function in my Excel sheet where the user can select multiple items from different listboxes.
To save the items I use an array. So in one case only 1 items off the array is filled, but another time maybe 3 items are filled in the array.
I use the array to search in a SQL database (this is string rva(i) in the code). But when the array is empty it results in an error.
This is what I have so far. (the rule at the bottom won't work also )
rc.Open "SELECT [Datum],[RvA_Nr], [RvA_Letter], [Afdeling], [EVAL], [Matrix], [Component], [AS3000], [AP04], [Rec] FROM dbo.QHSE_2ndline_history " _
& "WHERE [Afdeling] = '" & afd & "' AND [Datum] >= '" & datum1 & "' AND [Datum] <= '" & datum2 & "' AND " _
& "CASE WHEN '" & rva(1) & "' <> '' then [RvA_Nr] = '" & rva(1) & "' END AND" _
& "([Matrix] LIKE '%" & matrix(1) & "%' OR [Matrix] LIKE '%" & matrix(2) & "%' OR [Matrix] LIKE '%" & matrix(3) & "%' OR
[Code] .....

I have a SP search_post (e.g)
@id int,
@author varchar(40),
@keyword varchar(40),
select * from
posts
where
id = @id and author =@author and message like @keyword
in my case a user can choose to search by one or more of this elements.
what will be the best approach to write a statement that will account for the posibility of the user leaving some "parameters" empty, while also allowing for the posibility that all parameters could be filled
one approach I have thought out is this
if (@id IS NOT null)
select * from
posts where id = @id
if (@author IS NOT null)
select * from
posts where author= @author
if (@keyword IS NOT null)
select * from
posts where keyword = (@keyword
but this does not really take care of the posibility that all of them or some of them will be null while others will not
any suggestions ?

Background: Customer sale records are kept in table (userHistory) that records: bookID, userID, and salesDate.
Objective: To find all the customers that have purchased the same books as any given customer, say customer1. For example, customer1 bought books bookA, bookB, and bookC; the goal is to find all of the other customers who also bought these books.
My First Attempt:
SELECT DISTINCT UH1.userID
FROM userHistory as UH1, userHistory as UH2, userHistory as UH3
WHERE UH1.userid = UH2.userID
ANDUH2.userid = UH3.userID
ANDUH1.bookID = ‘bookA’
ANDUH2.bookID = ‘bookB’
ANDUH3.bookID = ‘bookC’
AND UH1.userID <> ‘customer1’
The problem here is that it cannot handle any more/less than 3 books. The above should work well for 3 books, but what if there are 2 books or 12 books? Does anybody have any suggested queries to handle a variable amount of books (eg joins)?
Thank you kindly.

We are trying to use the Import/export wizard to load a text file to a SQL Server 2005 database. The input file has a variable number of columns per row. For example, the first row has 3 columns, the second has 7, the third has 3, etc. The number of columns varies from 2 to 9 in the input file. The columns are separated by an uptick (`) and the rows are terminated by {CR}{LF}. We are using code page 1252. On processing, the wizard reads the first row (with 3 columns) ok, but then assumes all the other rows have 3 columns and parses the rows accordingly, ignoring the field and row terminators.
The process worked fine with SQL Server 2000. Is there some setting that we are missing, or some configuration on the database that we should be checking?
Thank You

Hi, I need to update a number of columns in a number of tables - I just don't know how many. In this case, I am updating all varchar fields and nvarchar fields to be converted to lower case. The problem is that the table structure is amended over time as columns are added programmatically, so I do not know which tables have which columns and if so which of them are varchars.
I can get a table of which fields I need to update using:
SELECT TABLE_NAME, COLUMN_NAME, ORDINAL_POSITION, DATA_TYPE
INTO tblTempLCase
FROM information_schema.columns
WHERE DATA_TYPE LIKE '%varchar'
and I can do the update with UPDATE tblxxx SET column = LOWER(column)
But what I don't know is how to step through my temporary table and do the updates. I can do it in ASP.NET, but that involves pushing commands and data between ASP and SQL, and will be too slow. How do I do it in SQL?
Thanks,
Dave Stephens

Hi,
I need to update a number of columns within a number of tables - I just don't know how many. In this case, I want to convert all varchar and nvarchar columns to lower-case versions of themselves. The problem is that the table structure is changed programatically, and so at any point in time I cannot be certain what fields are in which table, and what data type they are.
I know that I can get a lit of columns using:
SELECT TABLE_NAME, COLUMN_NAME, ORDINAL_POSITION, DATA_TYPE
INTO tblTempLCase
FROM information_schema.columns
WHERE DATA_TYPE LIKE '%varchar'
and do the update using:
UPDATE tblABCDE SET column = LOWER(column).
In ASP.NET I can pull in this temporary table using a SQL Data Adapter, and then step through the records to formulate the UPDATE statements and execute them all. However, I hope that this is possible in SQL too, so that I do not have to keep firing data/commands between ASP and SQL, as it should be quicker, and is also neater.
If so, how do you do it?
Thanks,
Dave Stephens

I have the following situation; I have one table (tblA) in which a new record just has been inserted. Once this insert is completed successfully, I want to insert a variable number of records into another table (tblB). The primary key of tblA is being used inside tblB as one of the columns in each insert. I’ve already been able to transfer the primary key, generated by the insert for tblA, pretty easy. But to make things a bit more complicated, the variable number of records to add is being decided by the outcome of a query based on an entry inside tblA (after the insert) and this is then being run on another table (tblC). The SELECT statement from tblC combined with the Select parameter from tblA will then decide how many records I have to insert. Sorry for the (perhaps) confusing way of writing this down, but I’ve been struggling with this for a couple of days now and I really need to get it working. Anybody who can help?Thanks in advance,Sunny Guam

I have a strongly typed dataset, and I need to be able to do a search on multiple values of a parameter. The problem is I don't know how many. I have a textbox that the user can enter search words in. The select string is built from the string of words that are entered, like this:For iCount = 0 To UBound(sArray) strSQL = strSQL & "Description LIKE '%" & sArray(iCount) & "%' OR "Next Can I do this is a dataset method?

I have a web page which passes back parameters to a stored procedure.
From the web page the user selects different clauses for the 'where' criteria.
Based upon the number of clause items in the parameters sent back, a select statement is built and executed.
In the stored procedure I have many if statements to chose the correct sql statement.
As the no of clauses in the where statement can vary, it can become messy script.
Has anyone dealt with this scenario. What is the best strategy ?
A simple illustation of this is as follows
A statement with two clauses :-
Select * from Sales where
user = 'John' and country = 'England'
A statement with three clauses :-
Select * from Sales where
user = 'John' and country = 'England' and County = 'Staffordshire'
The stored procedure would except three parameters and would build a string based on the number of actual where clases sent back

Using Microsoft query analyser SQL version 8, I believe.
Got a SQL table with a column that has NULLS in it. What I want to do is fill down the value in the row above based on a condition in another column (recordtype). Came up with the following code but unfortunately it only fills in the record directly below. Not those further down (variable number of NULL rows). Any idea how to get these to fill down? Suspect the answer may lie with block cursors but 1) I'm told they're slow (I have 2 and 1/2 million records in this table) and 2) I've never used cursors before!
________________
Update dbo.NSTS
Set dbo.NSTS.Number = NSTS_1.Number
FROM dbo.NSTS LEFT OUTER JOIN
dbo.NSTS AS NSTS_1 ON dbo.NSTS.[Id] = ((NSTS_1.[Id])+1)
WHERE dbo.NSTS.RecordType like '101' AND (dbo.NSTS.Number is null or dbo.NSTS.Number like '')
________________
Example of data table here:
ID RecordType Number
1 100 4325273182
2 101 NULL
3 101 NULL
4 101 NULL
5 100 4342684020
6 100 4342696800
7 100 4304028782
8 100 4305914743
9 101 NULL
10 101 NULL
11 100 4328179942
12 101 NULL
13 101 NULL
14 101 NULL
15 101 NULL
16 100 4329313804
17 100 4329874164
18 101 NULL
19 100 4330053764
20 101 NULL
_________________
I did get a cursor loop working but can only retrieve 1 row and (try as I might with the so called help examples) can't seem to pull down 2 rows at a time. Just can't seem to get it to accept this command at all: SQLSetStmtAttr(hStmt, SQL_ATTR_ROW_ARRAY_SIZE, (SQLPOINTER) 2 ,0).
Help would be very much appreciated!

Hi, i'm trying to port a pivot query from access to sqlserver.
I'm trying this query:
SELECT IDMerce, [1] AS [Department-1], [2] AS [Department-2], [3] AS
[Department-3], [4] AS [Department-4]
FROM (SELECT IDMerce, Pezzi, IDMagazzino
FROM Disponibilita) p PIVOT (sum(Pezzi) FOR
IDMagazzino IN ([1], [2], [3], [4])) AS pvt
this works, but in my case i don't know in advance how many transformations
i need, so there is a solution?
Thanks

I have a booking system which stores an event along with a start date and a finish date. I want to create a table which has a row for each day the event is on. I can find the number of days easily enough using a datediff function but I don't know how to translate this into that number of rows. My current thinking is to cross join the original table out to another temporary table with a large number of rows and use SQL2005 to only select the top 'x' rows, then use the rownumber of this temp table to add the required number of days to the StartDate to get each eventdate. Currently I use a loop to build the required table but there must be a way to get it all done in a single statement :)
Thanks
ORIGINAL DATA
EventID StartDate EndDate
1 1/1/08 1/1/08
2 20/1/08 22/1/08
REQUIRED DATA
EventID EventDate
1 1/1/08
2 20/1/08
2 21/1/08
2 22/1/08

Can a Sql Server SP have variable number of arguments??? If yes, can somebody point me to a resource demonstrating that??? I need to send variable number of arguments to some of my SPs & iterate them with either foreach or traditional for loop. Any support would be greatly appreciated.
If variable number of arguments are not feasible, then can I pass them as an array to the SP (again a Sample code would be desirable)???

Hi folks....
I am able to import a CSV file into a temporary table as long as I know the number of fields in the CSV file. Here is what I would like to do:
I would like to have a CSV file which has UP to 6 entries per row. I would like to insert each row into a table; if the there three fields, then I want to insert them into the first three columns to the temporary table. If there are four, then insert into the first four fields. Is this possible?
Does anyone have any suggestions?

I've got a table full of data like so:
varchar(MAX) as
'MSG|John|J|Smith EVN|2008-02-01|A03 ADD|101 Highland St|Mount Vernon|WA|55231 OBS|Flu|Severe OBS|Mumps|Mild'
To explain this more thoroughly, the data is organized into segments: MSG, EVN, ADD, and OBS.
Each message may have 1+ of each of these segments.
What I'd like to do is pull the contents of all OBS segments and put them into a table.
I know I can identify them using the regex of ' OBS|' but I'm not clear on how to capture anything but the first one easily. Programmatically, it's simple. SQL I'm not so sure.
Can anyone give me a gentle nudge in the right direction?
Thanks!

I have received a change request for a project i am working on which im unsure if possible or not.
at the minute i have a very simple sp that simply selects data from a table by passing in one parameter
CREATE PROCEDURE PHAR_SelectGrade
@int_ID int
AS
SELECT GradeID as ID, Grade as Description, RequiresText, SendEmail, Timestamp
FROM tbl8Grade
WHERE Obsolete=0
AND GradeID = @int_ID
ORDER BY Grade
the user now wants the option to select more than one grade type (there are 100's of different grades)
so they might decide they want to see details for 2 grades, 22 grades etc. these would be selected and stored in an array (via an asp.net project) and then the stored procedure is called from within a web service
my question is how would i pass this array into the stored procedure??
i am assuming i would need to do something as follows for sp syntax, but im stumped on how i pass my array of values into the sp from the webservice and then for the sp to read the array in SQL??
CREATE PROCEDURE PHAR_SelectGrade
@myArray <what datatype?>
AS
SELECT GradeID as ID, Grade as Description, RequiresText, SendEmail, Timestamp
FROM tbl8Grade
WHERE Obsolete=0
AND GradeID IN (@myArray)
ORDER BY Grade
any ideas are greatly appreciated. or maybe its just not possible?!?
Cheers,
Craig

Hi,
I have a repeater control which I populate with search results from SQL Server.
But I can't figure out how to cope with users who submit multiple search items and still use my stored procedure. Is this possible or do you have to build the query with a StringBuilder and execute it manually?
I'm using a stored procedure with parameters:
input parameters <-- PageSize & CurrentPage
output parameter --> TotalRecords
Am using a temporary table to store all records before Select-ing those required for the particular page.
If I compose the query manually then I can't figure out how to get TotalRecords back as a return parameter. Would appreciate help on this one.
Am hoping that stored procedures can cope with an unknown number of parameters.

I am fairly new to MSSQL. Looking for a answer to a simple question.
I have a application which passes in lot of stuff from the UI into a stored procedure that has to be inserted into a MSSQL 2005 database. All the information that is passed will be spilt into 4 inserts hitting 4 seperate tables. All 4 inserts will be part of a stored procedure that have to be in one TRANSACTION. All but one insert are straight forward.
The structure of this table is something like
PKID
customerID
email address
.....
customerID is not unique and can have n email addresses passed in. Each entry into this table when inserted into, will be passed n addresses (The number of email addresses passed is controlled by the user. It can be from 1..n). Constructing dynamic SQL is not an option. The SP to insert all the data is already in place. Typically I would just create the SP with IN parameters that I will use to insert into tables. In this case I can't do that since the number of email addresses passed is dynamic. My question is what's the best way to design this SP, where n email addresses are passed and each of them will have to be passed into a seperate insert statement? I can think of two ways to this...
Is there a way to create a variable length array as a IN parameter to capture the n email addresses coming in and use them to construct multiple insert statements?
Is it possible to get all the n email addresses as a comma seperated string? I know this is possible, but I am not sure how to parse this string and capture the n email addresses into variables before I construct them into insert statements.
Any other ways to do this? Thanks

Hi,
We are building an application with
a database that contains Jobs. These Jobs have properties like Name, Code etc.
and some custom properties, definable by the application admin. For bulk import
of Jobs, we want to allow the import of an Excel sheet with the columns Name,
Code and a variable amount of columns. If the header names of these columns in
the Excel sheet match the name of a custom property in the system we want to add
the value of that cell into the database as property
value.
In our Data Flow of our Import
Package in SSIS we added an Excel Source that points to a test excel sheet with
the Name and Code columns and €“ for this example - 3 custom property columns
(Area, Department, Job Family). When we configure the Excel Source in the Excel
Source Editor, we have the option to select the Columns from the Available
External Columns table. But here lays the problem, we do not know at design
time, what custom property columns to expect. We DO expect the Name and Code
columns, but the rest is uncertain at design-time.
That raises the question: Is there
some way to select all of any incoming columns (something like a SELECT * in
T-SQL)? This looks like a big problem since it would mean that the .DTSX XML that is
being generated at design-time would need to be updated at run-time to reflect
the variability of the columns that might be encountered while reading the excel
sheet.
Then, we thought, we could add a Script
Component to our data flow that passes some kind of DataSet (or DataReader) in
which we can walk through the columns ourselves? But then still, we miss the
option to include ANY of the columns while reading an Excel sheet (or any other
datasource by the looks of it)
We are aware of the option of
optional columns in combination with the RaggedRight option, but it seems that
we would have to put all of the columns of a row in just one column and then
extract all the columns later with Derived Columns. But then, since the source
import file is being prepared by an application admin, we want don€™t want to
burden him with this horrendous task of putting everything in one
column.
We would like to have some way of
iterating through all the columns, either in a Script Component or maybe with a
Pivot/Unpivot mechanism.
Does anyone have any suggestions? Are there other options we should have considered?

Hi there,
I have decided to move all my transaction handling from asp.net to stored procedures in a SQL Server 2000 database. I know the database is capable of rolling back the transactions just like myTransaction.Rollback() in asp.net. But what about exceptions? In asp.net, I am used to doing the following:
<code>Try 'execute commands myTransaction.Commit()Catch ex As Exception Response.Write(ex.Message) myTransaction.Rollback()End Try</code>Will the database inform me of any exceptions (and their messages)? Do I need to put anything explicit in my stored procedure other than rollback transaction?
Any help is greatly appreciated

Hi
I have a dataset with 2 columns, a rownumber and a servername - eg
rownumber servername
1 server1
2 server2
....
15 server15
I want to display the servernames in a report so that you get 3 columns - eg
server1 | server2 | server3
server4 | server5 | server6
...
server13 | server14 | server15
I have tried using multiple tables and lists and filtering the data on each one but this then makes formating very hard - i either end up with a huge gap between columns or the columns overlap
I have also tried using a matrix control but cant find a way to do this.
Does anybody know an easy way to do this? The data comes from sql 2005 so i can use a pivot clause on the dataset if somebody knows a way to do it this way. The reporting service is also RS2005
Thanks

I am writing a package that will process delimited flat files that will come in one of a few different versions. Within each flat file, the number of delimited columns will be the same, but each version of the file has a different number of columns. I have tried configuring the flat file data source to expect the version with the largest number of columns, but it will then throw away rows that have less than this number of columns (warning: There is a partial row at the end of the file).
Is it possible to use a single flat file data source that will work with all of the different width files?

Im trying to determine the best way to store data gathered from a form that a user will fill out online. The form is dynamic and is customized at run time based on group-specific criteria. The end result is a form that might have 3 extra text boxes, 2 extra sets of radio buttons and a freeform textbox, whereas for another group, there might be a slightly different set of input fields. Now comes the issue of storing this data. Since the fields can be somewhat dynamic, it could get tricky to define table columns for each possible input field. So Im considering storing the data as xml. Has anyone else had to build custom forms and ended up storing the data as xml ?

I want to load flat files into a single table. But the flat files can have variable number of columns upto a maximum of 10 columns. The table in my database has 10 columns in it. So in case if I load a flat file having 6 columns then rest of the columns in the table will have nulls. I don't want to use script task for this as I am not good in writing C#code.

Just curios,
I have four 72 GB Drive on a RAID 5
Disk Specs
IO/Second = 130 per disk
Speed RPM = 15 K
When I did a load test of inserting data into a table
with four Columns
Col1 INT
Col2 VARCHAR(32)
Col3 VARCHAR(4000)
Col4 DATETIME
I could insert around 1044 Inserts per second where as
I thought I could do max of 520 Inserts ( 130 * 4 ) because
each disk can only take 130 Inserts multiplied by 4 Disks
gives me a theoritical limit of 520.
Also How does the Query Analyser Connects to the datbase
Server.. does it use ODBC
Thx
